Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides an automatic can prevent clamping positioner of repeated drilling, as shown in figure 1, including work piece locating pin 1, fixation nut 2, the tee bend 3, pressure sensor 4, apron 5 and elbow clamp 6, work piece locating pin 1 is installed on the bottom plate 7 of drilling equipment through fixation nut 2, the conduction groove 11 is established to the ring on the lateral wall of work piece locating pin 1, and conduction groove 11 corresponds with the drilling position axial of work piece 9, set up the breather pipe with conduction groove 11 intercommunication in the work piece locating pin 1, and utilize tee bend 3 and pressure sensor 4 and gas source to be connected, elbow clamp 6 sets up on bottom plate 7, apron 5 sets up on elbow clamp 6, during the detection, work piece 9 cover is established on work piece locating pin 1, and utilize apron 5 to install work piece 9 on work piece locating pin 1.

In one embodiment, as shown in fig. 1, the end of the workpiece positioning pin 1 is chamfered. To facilitate the mounting of the workpiece 9 on the workpiece positioning pin 1.

In one embodiment, as shown in fig. 1, a drill guide 8 is disposed on the bottom plate 7, and a guide hole 81 for guiding the drill to move vertically is disposed on the guide 8. To guide the drill bit to drill the workpiece 9 to improve the drilling accuracy.

In one embodiment, as shown in FIG. 1, the elbow clip 6 is Misimi MC 01-1.

In one embodiment, as shown in fig. 1, the sealing gasket is arranged on the contact surface of the cover plate 5 and the workpiece 9. Wherein, the sealing gasket can be made of silica gel material. And a sealing gasket is additionally arranged to prevent the cover plate 5 from being in hard contact when the workpiece 9 is fixed so as to damage the end face of the workpiece 9. And improves the sealing property between the cover plate 5 and the workpiece 9.

In one embodiment, as shown in fig. 1, the vent pipe comprises a first pipe 12 and a second pipe 13 which are communicated, wherein the first pipe 12 is arranged radially, and the second pipe 13 is arranged axially. Through the arrangement of pipelines at two ends, the processing of the vent pipe is facilitated.

When the utility model is used, as shown in fig. 1, a workpiece 9 is sleeved on a workpiece positioning pin 1, a cover plate 5 is covered on the workpiece 9 through an elbow clamp 6, meanwhile, the workpiece 9 and a road system form a closed space, an air source is opened, compressed air is introduced, and the pressure in a pipeline is measured by a pressure sensor 4; when the workpiece 9 to be mounted is a machined workpiece, a closed space cannot be formed in the annular groove 11, the introduced compressed air flows out from the machined hole, and the pressure sensor does not give a signal of correct installation.
